I have an 945gzt-m v 1.0 and dont know were the pwr sw wire goes
Yes.
First, let's orient the view of the motherboard, so we are both looking at it the same way.
The processor is at the top middle, and the Front panel header, is to the very bottom right hand corner.
Right next to the motherboard mounting hole.
The Front Panel header goes across the bottom edge of the motherboard, lengthwise.
Looking at the top row of pins on the Front Panel header, No.2 Pin is at the far left. Pins 2, 4, 6, 8 and 10, go across the top.
Looking at the bottom row, No. 1 Pin is at the far left. Pins 1, 3, 5, 7, and 9, go across the bottom.
The power switch wires go to Pins 6 and 8.
The HDD LED wires go to Pins 1 and 3.
The power LED wires go to Pins 2 and 4.
On the power switch wires, the Positive (+) wire goes to Pin 6. Just in case this wire is marked.
(Doesn't really matter which way it goes, because it's a switch!)
On the HDD LED wires, the Positive (+) wires goes to Pin 1.
On the power LED wires, the Positive (+) wire goes to Pin 6.
